GEORGE PARIS, OF HARRISBURG, PENNSYLVANIA.

MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented April 9,1907.

Application tiled April l0, 1906. Serial No. 310,965-

To @ZZ whom, it may concern:

Be it known that I, GEORGE PARIs, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

My invention relates to leaf-turners, and has for its object to provide a compact instrument which will positively and quickly turn the leaves of sheet-music, either loose or bound in book form, inserted therein.

My invention consists of a device for turning the leaves of sheet-music, and comprises a housing with shelf adapted to be temporarily or permanently secured to the shelf of a piano, organ, or music-stand, a plurality of leaf-holders adapted to slide on a semicircular wire supported by the shelf of the housing, and means for successively operating said leaf-holders.

My invention further consists of the improvements hereinafter more fully set forth, and pointed out in the claims.

My invention will be more fully understood, taken in connection with the accompanying drawings, forming part hereof, and in which p Figure 1 is a front elevation of the leafturner secured to the shelf of a piano, organ, or music-stand and showing the leaf-holders, the wire supporting them, the housing, and the means for operating the leaf-holders. Fig. 2 is a plan view of the leaf-turner. Fig. 3 is a section on line 3 3 of Fig. 2. Fig. 4 is a section on line 4 4 of Fig. 2. Fig. 5 is a section on line 5 5 of Fig. 2, showing a pedal for operating the device; and Fig. 6 is a top and end view of the dog and pawl for engaging the individual leaf-holders.

Referring now to the drawings for a further description of my invention, A is the shelf of a piano, organ, or music-stand.

B is the housing attached by a hinge t to the shelf b of the leaf-turner for a purpose to be presently described. The shelf b/ is provided with a bead b2 to conform to the bead on the shelf A and with lugs b3 and thumbscrews t4 to fasten the leaf-turner to the shelf A. In front of the shelf t is secured the semicircular wire c, adapted to hold and guide the leaf-holders d' at one end. These leafholders d are made of thin sheet metal and are provided with ears d, so that the sheetmusic may be inserted between the body of the holder and these thereby.

In the rear of each leaf-holder is provided a lug d2 to separate the individual holders and allow thel gripping mechanism to take hold of them. On each end of the shelf b is arranged a support e for the holders d when the latter lay against each other and the shelf b. To turn the leaf-holders d and the sheet-music inserted therein from the righthand side, Figs. 1 and 2, to the left-hand side, or, in other words, to turn the leaf of sheet-music, the following devices have been provided:

In the housing B is arranged a stationary shaft g, and a gear-sector g, having fastened to it an oscillating lever g2, is loosely mounted on said shaft g and adapted to move up and down thereon. Oscillating motion is imparted to said gear-sector g and lever g2 by the gear-sectorf, pivoted to the housing B at f. To operate the lever g2 to swing in the direction of the arrow in Fig, 2, a cord i is secured with one end to the free end of the gear-sector f and led over a small pulley i', pivoted to the housing B, Figs. 2 and 5, and the other end of the cord is attached to a spring-operated pedal i2, which when depressed will actuate the lever g2. The return of the lever g9d to its normal position at the right-hand side of the leaf-turner is effected by a spring g4.

The free end of the lever g2 is provided with a dog g5, the upper edge 99 of which is in line with the lower edge of the leaf-holder d, so as to engage the individual holder and carry it around when the lever g2 is operated toward the left. A shoulder glo is provided on said dog g5 to limit the movement of the free end of the lever g2 when the latter moves toward the right and while the edge gv9 rides under the said holder.` To insure an eas engagement of the dog g5 with the holder d, the edge g9 is slanting downward, as shown at g, Figs. 5 and 6. A pawl g is pivoted to this dog g5 to engage the uppermost leafholder at the right-hand side of the turner, and as soon as the pedal L2 is depressed the said leaf-holder is transferred to the left-hand side of the turner. This pawl gr6 is prevented from turing completely around by the backstop or pin g?, and a spring g8 is employed to hold the pawl in a normal position. On the return movement of the lever g2 to its normal position at the right-hand side of the turner ears and firmly held IOO IOS

the wedge-shaped top of the pawl g tilts forl for transferring the leaf-holders from right to ward until the dog g5 strikes the face of the leaf-holder d, when the pawl g, influenced by the spring g8, engages the rear ofthe foremost leaf-holder and is ready to turn the same.

To release the dog and pawl from engagement with the leaf-holder l when it is near the left-hand side of the turner, the lever g2, with gear-sector g', is depressed on the shaft by a groove g3, Fig. 1, formed in the upper part of the housing B and by which the said lever' g2 is guided. This groove g8 or cam causes the lever g2 to be depressed sufficiently to release the leaf-holder al from the dog g5 and pawl gG and after the leaf-holder d has reached its support e at the left-hand side of the turner.

As before stated, the leaf-holders d are supported and guided at one end by the semicircular wire c, and during the transfer from right to left they are supported by the dog Ordinarily when only sheet-music is to be inserted into the holders d the single pages are entered between the body of the holder and the ears d without disturbing the app araatus; but when certain pages of a bound book are to be inserted into the holders d it becomes necessary to swing the lever g2 and gear-sectorf out of the way, so that the holders may be turned around the wire c. For this purpose the housing B is hinged to the shelf 1) and is held in normal position by the catch-lever lr, as clearly shown in Figs. 1 and 6. lf it is desired to insert certain pages of a book into the holders d, the housing B is released from the catch-lever 7c and swings downward about its hinge Z). The holders d are then brought about to the center of the wire c, and the leaves of the book, which latter rests on the shelf b, are then inserted one by one into the holders d and brought toward the right-hand side of the turner and rested on the support e on that side. After the desired number of leaves have been inserted into the holders d the housing B is brought into its normal position and held there by the catch 7c. The device is then in operative position Aand operates as hereinbefore described.

Having thus described the nature and ob jects of my invention, what l claim as new, and desire to secure by Letters Patent, is-

1. A music-leaf turner comprising a shelf, a housing hinged to said shelf, a semicircular wire guide secured to said shelf a support at each end of said shelf, a plurality of leaf.- holders normally supported by said wire guide and said supports, an oscillating lever left about the wire guide, means attached to l said lever for engaging the said holders and means for lowering and raising the said lever,

substantially -as and for the purposes set l forth. l 2.
